<?Pub Dtl?>This paper reports the first co-design configuration of a power amplifier (PA) in cascade with a high- bandpass filter. By matching the filter's input port directly to the transistor's drain node, the conventional output matching network (OMN) of a PA is entirely eliminated. This leads to smaller size/volume, minimized loss, and enhanced overall performance. To enable this co-design...
A unique GaN power amplifier (PA) with an integrated evanescent-mode resonator as its output matching network is presented in this paper. Instead of matching the output of the GaN transistor to 50 Ω and connecting it to a 50-Ω bandpass filter, the GaN is directly integrated with a one-pole filter thus eliminating the conventionally-employed output matching network after the GaN transistor. This leads...
